"They came through a full training session this morning. It wasn't a very hard session, but they will both be in the squad.

"It's important for us to have these two players of quality who can change a game. I'm not surprised they are available because the medical staff have done a good job and the players have been working really hard with the physios to get fit."

Reds' skipper Gerrard recently underwent groin surgery, while striker Torres has been hampered by a hamstring strain picked up against Aston Villa a few weeks ago.

Meanwhile, Argentina midfielder Javier Mascherano has warned his Liverpool team-mates that a win against Sir Alex Ferguson's reigning champions is essential in their bid to prove they have serious title credentials.

"This is a very important period, we have a lot of important games coming up after the international break - especially the first one against United," said Mascherano.

"More than three points ride on these games as it proved when we lost at home to United last season.

"It's a match we need to win if we want to compete for the title. We can do that and push for honours. The fans deserve it."

Fergie confirms Ronaldo is fit

Sir Alex Ferguson confirmed his entire first-team squad is now fit ahead of the Anfield trip, meaning that Cristiano Ronaldo is primed for a Champions League comeback against Villarreal at Old Trafford on Wednesday.

The Portuguese winger will not travel with the squad this weekend as he completes his recovery from ankle surgery, but is due to come back to action ahead of schedule.
